BRIDGEPORT -- The 40-year old Connecticut man who died of an apparent drug overdose Friday at the Gathering of Vibes festival had a history of marijuana arrests.

Christopher Cragin, 40, who most recently lived on Garden Street in New Haven and Kings Highway in North Haven, was identified by police Saturday as the victim of apparent drug overdose.

Cragin was found unresponsive at the festival's campgrounds as day two of the rock fest got into full swing. Police continue to investigate the death and the state medical examiner is working to determine the exact cause of death.

Bridgeport police spokesman Bill Kaempffer said an autopsy was scheduled for this weekend.

According to news reports, Wallingford police arrested Cragin in September 2011 for making and selling marijuana brownies, along with a 39-year-old woman. Police discovered 11 ounces of marijuana, more than 30 brownies, packaging materials and ingredients for more brownies.

Cragin was detained on a $25,000 bond and also arrested for two outstanding warrants related to motor vehicle charges. Cragin and the woman were living in a Beth Ann Court apartment at the time.

In November 2011, Cragin was arrested by North Haven police for growing marijuana at a rental property on Kings Highway in North Haven. Police removed UV growing lights, irrigation materials, drying racks, packaging equipment and a small amount of marijuana.

Cragin, along with the same woman who was arrested with him two months earlier for allegedly selling pot brownies, was charged with possession of drug paraphernalia, possession of marijuana with intent to sell, operating a drug factory and conspiracy to operate a drug factory and held on $35,000 bond.

After Cragin's body was found at the Vibes festival Friday, Bridgeport police initially reported the victim to be a man in his late 20s based on items located at the scene, Kaempffer said Saturday.

Kaempffer also said police interviewed an unnamed woman in connection with the investigation. It was not clear if the woman was the same one who was involved in the earlier incidents with Cragin.

Cragin was pronounced dead at a local hospital. Officials have not yet determined what substance(s) Cragin apparently overdosed on Friday.

"We're going to rely on the expertise of the medical examiner to determine that, and it's going to take some time," Kaempffer said, referring to Cragin's toxicology results. "Based on what detectives observed, this is being treated as a drug overdose."

Wallingford police have assisted Bridgeport police with the case.

The apparent overdose Friday marked the third such death since 2009 at the Vibes, a festival that largely draws its appeal from the reincarnation of the music and culture of the hippie era.

In the early morning hours of July 26, 2009, Jay Caliro, 29, of East Meadow, N.Y., was found dead. His death was later attributed to an accidental overdose, marking the first fatality in the history of the festival.

The following year, 23-year-old Elizabeth Meryl Miller, of Memphis, Tenn., was found having a seizure inside the campground and a Bridgeport police officer revived her.

She was transported to St. Vincent's Medical Center, where she died two days later. An autopsy later determined her death resulted from "multiple drug toxicity."

Festival organizers saw a greater city police presence in the wake of the 2009 Vibes, which brought the event under law enforcement scrutiny due to the prevalence of nitrous oxide at the festival that year and questions about how confiscated narcotics were handled by security.

The FBI investigated the availability of the gas after more than 100 confiscated canisters of nitrous oxide went missing. Vibes organizer Ken Hays told the Connecticut Post in 2010 that the festival had provided documents to investigators.

The city also instituted an ordinance banning nitrous oxide, which is commonly known as "laughing gas" and is typically sold inside balloons.

While drug use is something of an accepted part of the festival for participants, the death Friday brought a lurking danger to light.
